Systems and methods for determining an actual driver of a vehicle based at least in part upon telematics data

ABSTRACT

The present embodiments may relate to determining an actual driver of a vehicle based upon telematics data. For instance, a driver identification (DI) computing device may be configured to: (1) receive a first plurality of measurements captured at a first user device during a trip taken by a vehicle; (2) receive a second plurality of measurements captured at a second user device during the trip; (3) determine, based upon the measurements, that the user devices are within the vehicle during the trip; (4) calculate a respective enhanced geographic location measurement for each of the measurements based upon the measurements; (5) determine, based upon the enhanced geographic location measurements, a predicted position of the second user device relative to the first user device; and (6) identify, from among the user devices, a driver user device based upon the predicted position of the second user device relative to the first user device.

FIELD OF THE INVENTION

The present disclosure relates to systems and methods for determining a driver of a vehicle, and more particularly, to systems and methods for determining a driver of a vehicle based at least in part upon global positioning system (GPS) data, gyroscope data, accelerometer data, and/or other telematics data.

BACKGROUND

Satellite navigation systems such as global positioning system (GPS) utilize satellites to provide geo-spatial positioning for a variety of applications. A GPS-equipped device may provide a location of the device with respect to, for example, a geographic coordinate system and/or geographic landmarks (e.g., streets, political entities, points of interest, etc.). Current GPS-equipped devices are generally not capable of determining the exact location of the device, but rather provide an estimate of the device's current location subject to some degree of error. For example, atmospheric effects (e.g., ionospheric delay) and/or artificial interference (e.g., a presence of metal and/or electromagnetic devices) may introduce error to a GPS-based determination of location. Accordingly, for applications that need a precise determination of location, a method of enhancing GPS measurements is desirable.

For example, some applications may benefit from an ability to identify of a driver of a vehicle for a trip using devices (e.g., mobile devices) carried by persons in the vehicle. Identifying the driver may be useful in applications that utilize telematics data to assess the driver of the vehicle, such as for insurance purposes. In such applications, the driver of the vehicle for a trip must be distinguished from passengers, so that telematics data captured during the trip may be used to assess how the driver is driving and not incorrectly assign the driver's driving tendencies to that of the passengers. However, currently available GPS technology lacks the precision to make an identification of an actual driver of a vehicle based on measured geographic coordinates alone.

BRIEF SUMMARY

Some embodiments of the present disclosure may use, for example, Kalman filtering and/or machine learning techniques to enhance geographic location measurements made by a global positioning system, such that the enhanced geographic location measurements may be used to identify a user device corresponding to the actual driver of the vehicle and not devices associated with passengers of the vehicle. In some embodiments, a usage-based insurance policy may be applied to the identified driver of the vehicle.

DETAILED DESCRIPTION OF THE DRAWINGS

The present embodiments may relate to, inter alia, systems and methods for identifying a driver of a vehicle for a trip. In some embodiments, the systems and methods described herein may include receiving measurements of geographic location and other telematics data (e.g., acceleration, velocity, orientation, etc.) from a plurality of user devices (e.g., mobile devices) or other sensors present on the vehicle during the trip. Enhanced geographic location measurements may be calculated from the received measurements using a Kalman filter and telematics data. The enhanced geographic location measurements may then be used to determine a relative location of the plurality of user devices and calculate a probability for each user device that the user device corresponds to the driver of the vehicle. In one exemplary embodiment, the process may be performed by a driver identification (DI) computing device.

In some embodiments, the systems and methods described herein may additionally or alternatively include receiving, along with the measurements of geographic coordinates, telematics data (e.g., accelerometer and/or gyroscope measurements), and using the measured geographic coordinates and telematics data to calculate a probability for each user device that the user device corresponds to the driver of the vehicle.

As described below, systems and methods described herein generate enhanced geographic coordinate measurements to determine a probability that a user device corresponds to the actual driver of the vehicle as opposed to one of the passengers of the vehicle. As used herein, “driver” refers to a person actually driving a vehicle, and “passenger” refers to any person present in a vehicle that is not driving. By so doing, the driver of the vehicle for a particular trip may be identified.

In some exemplary embodiments, the systems and methods may be used to implement a usage-based insurance platform. In a usage-based insurance policy, an insurance premium corresponds to a driver's actual driving behavior. For example, the insurance premium may be based in part upon telematics data collected from a user device associated with the driver. It is thus advantageous to determine when a policy holder is actually driving a vehicle and when the policy holder is merely a passenger. By identifying a driver of a vehicle for a trip, the systems and methods enable telematics data collected for the trip to be applied in analyzing the identified driver.

Examples of Receiving Geographic Location Data and Telematics Data from User Devices

The DI computing device may receive geographic coordinate data and/or telematics data from a plurality of user devices (e.g., mobile devices and/or other sensors mounted on or within the vehicle). The plurality of user devices may include components for capturing and generating data, such as a GPS device, an accelerometer, and/or any other device capable of capturing data (e.g., a gyroscope). The DI computing device may use the received geographic coordinate data and telematics data to determine a location of one of the plurality of user devices with respect to the other user devices.

The plurality of user devices may be equipped with, for example, a GPS device. The GPS device may utilize GPS techniques to determine a measurement of geographic coordinates of the corresponding user device. Because some factors (e.g., atmospheric effects) may reduce the precision of the GPS device, the GPS device may return, for example, an error estimate along with the measured geographic location. The measured geographic location and error estimate may provide an area (e.g., a radius around the measured geographic location) where the user device may be located with a probability above a threshold probability.

The plurality of user devices may also be equipped with, for example, an accelerometer and/or a gyroscope. The accelerometer may be capable of measuring a linear and/or angular acceleration of the corresponding user device at a given moment in time. The gyroscope may be capable of determining an orientation of the user device. Accordingly, the accelerometer and gyroscope together may be used to determine a direction of acceleration of the user device. Data generated by the accelerometer and gyroscope may be used (e.g., by the DI computing device or user device) to generate telematics data (e.g., a location, orientation, acceleration, velocity, etc.) of the corresponding user device. Such telematics data may be used by the DI computing device, for example, to generate an enhanced measurement of the geographic location of the user device to determine whether the user device corresponds to the driver of the vehicle for the trip, with a passenger in the vehicle, or with another driver driving closely to the candidate vehicle (e.g., the vehicle being analyzed by the DI computing device).

Examples of Calculating an Enhanced Geographic Location Measurement Using at Least a Kalman Filter

The DI computing device may generate an enhanced geographic location measurement using a Kalman filter. A Kalman filter uses a series of measurements (e.g., geographic location measurements) containing statistical noise to produce estimates (e.g., the enhanced geographic location measurements) that tend to be more accurate than those based on a single measurement alone. A Kalman filter produces an estimate of a current state (e.g., a geographic location) and an uncertainty associated with the estimate, and when the next measurement is observed, updates the estimate using a weighted average, with more weight being given to estimates with less uncertainty. The enhanced geographic location measurement may be sufficiently precise to determine a relative position of the user devices over a period of time, which may be used to identify a user device corresponding to the driver of the vehicle.

To apply the Kalman filter, the DI computing device may analyze each measured geographic location with respect to the previous measurement. For each current geographic location measurement, the DI computing device may calculate an estimated geographic location measurement based upon a previous geographic location and telematics data. For example, the DI computing device may generate the geographic location estimate by integrating an acceleration value (e.g., a magnitude and direction of acceleration) associated with the previous geographic location measurement over a period of time between measurements to determine a displacement estimate (e.g., a displacement vector) from the previous geographic location, and add the displacement estimate to the previous geographic location measurement to determine the estimated geographic location measurement.

The DI computing device may then calculate the enhanced geographic location measurement by taking a weighted average of the current geographic location measurement and the estimated geographic location measurement. The weights assigned to the current and estimated geographic location measurements may be based, for example, on a predicted error of the current and estimated geographic location measurements, where a lesser predicted error corresponds to a greater weight.

Examples of Determining a Relative Position of User Devices Based at Least in Part Upon Enhanced Geographic Location Measurements

In some exemplary embodiments, the DI computing device may determine a relative position of user devices based at least in part upon the generated enhanced geographic location measurements. The relative location may be, for example, a distance vector from a reference user device and/or a map of relative locations of user devices traveling together. In some embodiments, the DI computing device may utilize machine learning techniques to determine a relative position of the user devices based upon geographic location measurements.

For example, the DI computing device may determine that a first user device and a second user device are traveling in the same vehicle based on a determination that, over time, the first user device and the second user device have the same direction of travel, and the relative positions of the first user device and second user device remain constant with respect to the direction of travel. The DI computing device may further determine that the second user device is on average one meter to the right of and zero meters behind the first user device. In some embodiments, the DI computing device may generate a map depicting the relative position of the first user device and the second user device showing, for example, the second user device being one meter to the right of the first user device.

In some embodiments, the DI computing device may utilize machine learning techniques to determine the relative position of the user devices based upon telematics data. For example, the DI computing device may identify a certain pattern of received geographic location measurements from a first user device and a second user device as indicative of the first user device having a certain position relative to the second user device. When the DI computing device receives geographic location data that matches such a pattern, the DI computing device may determine the relative position of the user devices based on the pattern.

Examples of Determining a Relative Position of User Devices Based at Least in Part Upon Telematics Data

In some exemplary embodiments, the DI computing device may determine a relative position of user devices based at least in part upon telematics data received from the user devices. Such telematics data may include, for example, the measured geographic location, an acceleration, a velocity, and/or an orientation of the user device. The relative location may be, for example, a distance vector from a reference user device and/or a map of relative locations of user devices traveling together.

For example, the DI computing device may determine that a first user device and a second user device are traveling in the same vehicle based on a determination that, over time, the first user device and the second user device are sufficiently proximate to each other have the same direction of travel. The DI computing device may then use telematics data to determine a relative position of the second user device with respect to the first user device.

In some embodiments, the DI computing device may use telematics data corresponding to horizontal movement (e.g., turning) of the vehicle to determine relative position of the user devices. For example, assume a first user device and a second user device are present in a vehicle, where the first user device is in a left (e.g., driver seat) position and the second user device is in a right (e.g., front passenger seat) position. If the vehicle makes a right turn, the first user device has a longer turning radius than the second user device. As a result, the first user device will experience a greater angular acceleration than the second user device as a result of the right turn of the vehicle. Accordingly, acceleration data measured by the accelerometer and gyroscope onboard the first user device and the accelerometer and gyroscope onboard the second user device may be used by the DI computing device to determine that the first user device is to the left of the second user device with respect to the direction of forward movement of the vehicle.

In some embodiments, the DI computing device may use telematics data corresponding to vertical movement (e.g., moving up and/or down inclines) of the vehicle to determine relative position of the user device. For example, assume a first user device and a second user device are present in a vehicle, where the first user device is in a front position and the second user device is in a rear position. If the degree of incline at which the vehicle is moving changes (e.g., the vehicle begins to move up or down a hill, over a bump, etc.), the first user device will experience a change in vertical acceleration before the second user device. Accordingly, the DI computing device may analyze the vertical acceleration of the first user device and second user device over time to determine that there is a delay between vertical acceleration of the first user device and the vertical acceleration of the second user device. Because this delay is related to the relative position of the first user device and the second user device and the forward speed at which the vehicle is traveling, the DI computing device may use this information to determine that the first user device is a certain distance forward of the second user device with respect to the direction of forward movement of the vehicle.

In some embodiments, the DI computing device may utilize machine learning techniques to determine the relative position of the user devices based upon telematics data. For example, the DI computing device may identify a certain pattern in telematics data as indicative of a first user device having a certain position relative to a second user device. When the DI computing device receives telematics data that matches such a pattern, the DI computing device may determine the relative position of the user devices based on the pattern.

Examples of Identifying a Driver Based at Least in Part Upon a Relative Position of User Devices

The DI computing device may identify the driver based upon a relative position of user devices. In some embodiments, the DI computing device may utilize, for example, machine learning techniques to determine a probability that each analyzed user device corresponds to the vehicle. The DI computing device may then identify the user device having the highest probability of corresponding to the driver of the vehicle as being the user device associated with the driver of the vehicle.

For example, the DI computing device may determine, based upon a determined relative position of a first user device and a second user device, that the first user device has an 80 percent chance of corresponding to a driver of the vehicle, the second user device has a 10 percent chance of corresponding the driver, and that there is a 10 percent chance that both the first user device and the second user device do not correspond to the driver. The DI computing device may identify the first user device as corresponding to the driver of the vehicle.

In some embodiments, the DI computing device may verify the identification of the driver. For example, the DI computing device may transmit a verification message to the first user device via a text message and/or via a mobile application (app) running on the first user device. The message may include an indication that the first user device has been identified as corresponding to the driver and requesting a user associated with the first user device confirm the identification. If the user responds in the affirmative, the DI computing device may identify the first user device as corresponding to a driver. If the user responds in the negative, the DI computing device may identify another user device, such as the next most likely user device (e.g., the second user device), as the user device corresponding to the driver. In some embodiments, the DI computing device may use the confirmation responses to improve a machine learning model used to determine the relative position of user devices and/or identify the user device corresponding to the driver.

Exemplary Insurance Applications of Identifying a Driver

In some exemplary embodiments, the DI computing device may be used to implement a usage-based insurance platform. In a usage-based insurance policy, an insurance premium corresponds to a driver's actual driving behavior. For example, the insurance premium may be based in part upon telematics data collected from a user device associated with the driver. Thus, for usage-based insurance, it is important to determine when the insured is actually driving the vehicle. By identifying a driver of a vehicle for a trip, the DI computing device enables telematics data collected for the trip to be applied in analyzing the identified driver.

At least one of the technical problems addressed by this system may include: (i) inability of a GPS device to provide a geographic location measurement sufficiently precise to be used to identify the driver of a vehicle; (ii) inability of a computing device to automatically identify a driver of a vehicle based upon telematics data; (iii) inefficiency in identifying a driver of a vehicle due to an inability of a computing device to automatically identify a driver of the vehicle based upon telematics data; (iv) inefficiency in providing usage-based insurance coverage due to an inability of a computing device to automatically identify the driver of a vehicle in order to apply telematics data associated with the trip to a usage-based insurance policy associated with the driver.

A technical effect of the systems and processes described herein may be achieved by performing at least one of the following steps: (i) receiving, from a first user device, a first plurality of measurements periodically captured at the first user device during a trip taken by a vehicle; (ii) receiving, from a second user device, a second plurality of measurements periodically captured at the second user device during the trip; (iii) determining, based upon the first plurality of measurements and the second plurality of measurements, that the first user device and the second user device are within the vehicle during the trip; (iv) calculating, a respective enhanced geographic location measurement for each of the first plurality of measurements and each of the second plurality of measurements based upon the first plurality of measurements and the second plurality of measurements; (v) determining, based upon the enhanced geographic location measurements, a predicted position of the second user device relative to the first user device with respect to a forward direction of travel of the vehicle; and (vi) identifying, from among the first user device and the second user device, a driver user device corresponding to a driver based upon the predicted position of the second user device relative to the first user device.

The technical effect achieved by this system may be at least one of: (i) ability of a GPS device to provide a geographic location measurement sufficiently precise to be used to identify the driver of a vehicle; (ii) ability of a computing device to automatically identify a driver of a vehicle based upon telematics data; (iii) increased efficiency in identifying a driver of a vehicle due to an ability of a computing device to automatically identify a driver of the vehicle based upon telematics data; (iv) increased efficiency in providing usage-based insurance coverage due to an ability of a computing device to automatically identify the driver of a vehicle in order to apply telematics data associated with the trip to a usage-based insurance policy associated with the driver.

Exemplary System for Identifying a Driver of a Vehicle

FIG. 1 depicts an exemplary driver identification (DI) system 100. DI system 100 may include a DI computing device 102. DI computing device 102 may include a database server 106. DI computing device 102 may be in communication with, for example, one or more of a database 108, a first user device 110, and/or a second user device 112. First user device 110 and second user device 112 may be, for example, mobile devices. In some embodiments, DI computing device 102 may communicate with additional user devices similar to first user device 110 and second user device 112. In some embodiments, DI computing device may be associated with, for example, an insurer providing a usage-based insurance policy to individuals associated with first user device 110 and/or second user device 112.

DI computing device 102 may receive geographic coordinate data and/or telematics data from first user device 110, second user device 112 and/or other sensors. First user device 110 and second user device 112 may include components for capturing and generating data, such as a GPS device 114, an accelerometer 116, a gyroscope 118, and/or any other device capable of capturing data. DI computing device 102 may use the received geographic coordinate data and telematics data to determine a location of one of first user device 110 and second user device 112 with respect to the other user device.

First user device 110 and second user device 112 may be equipped with, for example, GPS device 114. GPS device 114 may utilize GPS techniques to determine a measurement of geographic coordinates of the corresponding user device. Because some factors (e.g., atmospheric effects) may reduce the precision of GPS device 114, GPS device 114 may return, for example, an error estimate along with the measured geographic location. The measured geographic location and error estimate may provide an area (e.g., a radius around the measured geographic location) where the corresponding user device may be located with a probability above a threshold probability.

First user device 110 and second user device 112 may also be equipped with, for example, accelerometer 116 and/or gyroscope 118. Accelerometer 116 may be capable of measuring a linear and/or angular acceleration of the corresponding user device at a given moment in time. Gyroscope 118 may be capable of determining an orientation of the user device. Accordingly, accelerometer 116 and gyroscope 118 together may be used to determine a direction of acceleration of the user device. Data generated by accelerometer 116 and gyroscope 118 may be used (e.g., by DI computing device 102 or first user device 110 and second user device 112) to generate telematics data (e.g., a location, orientation, acceleration, velocity, etc.) of the corresponding user device. Such telematics data may be used by DI computing device 102, for example, to generate an enhanced measurement of the geographic location of the user device to determine whether the user device corresponds to the driver of the vehicle for the trip or with a passenger in the vehicle, or with a another driver driving closely to the candidate vehicle (e.g., the vehicle being analyzed by DI computing device 102).

DI computing device 102 may generate an enhanced geographic location measurement using a Kalman filter. A Kalman filter uses a series of measurements (e.g., geographic location measurements) containing statistical noise to produce estimates (e.g., the enhanced geographic location measurements) that tend to be more accurate than those based on a single measurement alone. A Kalman filter produces an estimate of a current state (e.g., a geographic location) and an uncertainty associated with the estimate, and when a measurement corresponding to the current state is observed, updates the estimate using a weighted average, with more weight being given to estimates with less uncertainty. The enhanced geographic location measurement may be sufficiently precise to determine a relative position of first user device 110 and second user device 112 over a period of time, which may be used to identify a user device corresponding to the driver of the vehicle.

To apply the Kalman filter, the DI computing device 102 may analyze each measured geographic location with respect to the previous measurement. For each current geographic location measurement, DI computing device 102 may calculate an estimated geographic location measurement based upon a previous geographic location and telematics data. For example, DI computing device 102 may generate the geographic location estimate by integrating an acceleration value (e.g., a magnitude and direction of acceleration) associated with the previous geographic location measurement over a period of time between measurements to determine a displacement estimate (e.g., a displacement vector) from the previous geographic location, and add the displacement estimate to the previous geographic location measurement to determine the estimated geographic location measurement.

DI computing device 102 may then calculate the enhanced geographic location measurement by taking a weighted average of the current geographic location measurement and the estimated geographic location measurement. The weights assigned to the current and estimated geographic location measurements may be based, for example, on a predicted error of the current and estimated geographic location measurements, where a lesser predicted error corresponds to a greater weight.

In some exemplary embodiments, DI computing device 102 may determine a relative position of first user device 110 and second user device 112 based at least in part upon the generated enhanced geographic location measurements. The relative location may be, for example, a distance vector from a reference user device (e.g., first user device 110) and/or a map of relative locations of first user device 110 and second user device 112 traveling together. In some embodiments, DI computing device 102 may utilize machine learning techniques to determine a relative position of first user device 110 and second user device 112 based upon the geographic location measurements.

For example, DI computing device 102 may determine that first user device 110 and second user device 112 are traveling in the same vehicle based on a determination that, over time, first user device 110 and second user device 112 have the same direction of travel, and the relative positions of first user device 110 and second user device 112 remain constant with respect to the direction of travel. DI computing device 102 may further determine that second user device 112 is on average one meter to the right of and zero meters behind first user device 110. In some embodiments, DI computing device 102 may generate a map depicting the relative position of first user device 110 and second user device 112 showing, for example, second user device 112 being one meter to the right of first user device 110.

In some embodiments, DI computing device 102 may utilize machine learning techniques to determine the relative position of first user device 110 and second user device 112 based upon telematics data. For example, DI computing device 102 may identify a certain pattern of received geographic location measurements from first user device 110 and second user device 112 as indicative of first user device 110 having a certain position relative to second user device 112. When DI computing device 102 receives geographic location data that matches such a pattern, DI computing device 102 may determine the relative position of first user device 110 and second user device 112 based on the pattern.

In some exemplary embodiments, DI computing device 102 may determine a relative position of first user device 110 and second user device 112 based at least in part upon telematics data received from first user device 110 and second user device 112. Such telematics data may include, for example, the measured geographic location, an acceleration, a velocity, and/or an orientation of first user device 110 and second user device 112. The relative location may be, for example, a distance vector from a reference user device (e.g., first user device 110) and/or a map of relative locations of first user device 110 and second user device 112 traveling together.

For example, DI computing device 102 may determine that first user device 110 and second user device 112 are traveling in the same vehicle based on a determination that, over time, first user device 110 and second user device 112 are sufficiently proximate to each other have the same direction of travel. DI computing device 102 may then use telematics data to determine a relative position of second user device 112 with respect to first user device 110.

In some embodiments, DI computing device 102 may use telematics data corresponding to horizontal movement (e.g., turning) of the vehicle to determine relative position of the user devices. For example, assume first user device 110 and second user device 112 are present in a vehicle, where first user device 110 is in a left (e.g., driver seat) position and second user device 112 is in a right (e.g., front passenger seat) position. If the vehicle makes a right turn, first user device 110 has a longer turning radius than second user device 112. As a result, first user device 110 will experience a greater angular acceleration than second user device 112 as a result of the right turn of the vehicle. Accordingly, acceleration data measured by accelerometer 116 and gyroscope 118 onboard first user device 110 and accelerometer 116 and gyroscope 118 onboard second user device 112 may be used by DI computing device 102 to determine that first user device 110 is to the left of second user device 112 with respect to the direction of forward movement of the vehicle.

In some embodiments, DI computing device 102 may use telematics data corresponding to vertical movement (e.g., moving up and/or down inclines) of the vehicle to determine relative position of first user device 110 and second user device 112. For example, assume first user device 110 and second user device 112 are present in a vehicle, where first user device 110 is in a front position and second user device 112 is in a rear position. If the degree of incline at which the vehicle is moving changes (e.g., the vehicle begins to move up or down a hill, over a bump, etc.), first user device 110 will experience a change in vertical acceleration before second user device 112. Accordingly, DI computing device 102 may analyze the vertical acceleration of the first user device 110 and second user device 112 over time to determine that there is a delay between vertical acceleration of first user device 110 and vertical acceleration of the second user device 112. Because this delay is related to the relative position of first user device 110 and second user device 112 and the forward speed at which the vehicle is traveling, DI computing device 102 may use this information to determine that first user device 110 is a certain distance forward of second user device 112 with respect to the direction of forward movement of the vehicle.

In some embodiments, DI computing device 102 may utilize machine learning techniques to determine the relative position of the user devices based upon telematics data. For example, DI computing device 102 may identify a certain pattern in telematics data as indicative of first user device 110 having a certain position relative to second user device 112. When DI computing device 102 receives telematics data that matches such a pattern, DI computing device 102 may determine the relative position of first user device 110 and second user device 112 based on the pattern.

DI computing device 102 may identify the driver based upon a relative position of user devices. In some embodiments, DI computing device 102 may utilize, for example, machine learning techniques to determine a probability that first user device 110 and second user device 112 corresponds to the driver of vehicle. DI computing device 102 may then identify the user device having the highest probability of corresponding to the driver of the vehicle as being the user device associated with the driver of the vehicle.

For example, DI computing device 102 may determine, based upon a determined relative position of first user device 110 and second user device 112, that first user device 110 has an 80 percent chance of corresponding to a driver of the vehicle, second user device 112 has a 10 percent chance of corresponding the driver, and that there is a 10 percent chance that both first user device 110 and second user device 112 do not correspond to the driver. DI computing device 102 may identify first user device 110 as corresponding to the driver of the vehicle.

In some embodiments, DI computing device 102 may verify the identification of the driver. For example, DI computing device 102 may transmit a verification message to first user device 110 via a text message and/or via a mobile application (app) running on first user device 110. The message may include an indication that first user device 110 has been identified as corresponding to the driver and requesting a user associated with first user device 110 confirm the identification. If the user responds in the affirmative, DI computing device 102 may identify first user device 110 as corresponding to a driver. If the user responds in the negative, DI computing device 102 may identify another user device, such as the next most likely user device (e.g., second user device 112), as the user device corresponding to the driver. In some embodiments, DI computing device 102 may use the confirmation responses to improve a machine learning model used to determine the relative position of user devices and/or identify the user device corresponding to the driver.

In some exemplary embodiments, DI computing device 102 may be used to implement a usage-based insurance platform. In a usage-based insurance policy, an insurance premium corresponds to a driver's actual driving behavior. For example, the insurance premium may be based in part upon telematics data collected from a user device associated with the driver. Thus, for usage-based insurance, it is important to determine when the insured is actually driving the vehicle. By identifying a driver of a vehicle for a trip, DI computing device 102 enables telematics data collected for the trip to be applied in analyzing the identified driver.
